:shock: so to save you pressing extra unnecessary buttons, you press extra unnecessary buttons?

Nope, I cannot connect the dots here.
It's not about pressing unnecessary button, it's about not knowing beforehand if another number or an operand will follow.

I think I must just be old-school but reaching for the calculator is the last stage in my thinking. Wouldn't dream of plugging numbers in without a clear vision of what I'm doing with them.
I don't think it is about being old-school, different people have different way of working. Of course when there is a clear vision beforehand this "trick" is not needed, but when I do my thinking "in live" this is useful.

Until you know what will follow, simply leave the numeric input open ... :roll:

Different people may have different ways in their lifes ... but see above. :mrgreen:

I'm just baffled by using EXIT for the reasons presented here. I don't see the point. None of the 'advantages' presented here are of benefit to me at all.

Maybe other folk find using EXIT in these ways helpful. If so, good for you.

But I don't get it.

No-one's forcing you to use it! You could put a "NOP" sticker over it if it helps! :D

Sure. It's what meaning one puts to it. It may be "EXIT operation of inputting a number" for example. Besides it is at convenient location to terminate an entry - rather that travelling all the way to the ENTER. Now I started thinking of EXIT as ENTER without stack lift - what exactly is your problem with that?

I personally prefer using SPC on HP48 instead of ENTER on multiple number input which gives me the opportunity to check and immediately correct it.
EXIT on HP42 is kinda similar, RPN imitation of RPL style entry.

Is it how you read it? Very funny :) Do you do stand-up comedy for living?
